Hi Dennis
I had a Tyros a PSR3000 and a Midjay all at the same time. They are all three fine instruments in their own way. You will really need to get your hands on one and test it yourself to see if you like the styles, voices and OS and if it meets your individual needs.
Nobody can really tell you which one is better. It's a very individual thing. Many places have a 30 day trial. That would be the way to go.
